First use .Equals() to check for equality. == checks that the references
match whereas .equals checks the values match.

The error message is telling you what's wrong, your checking an int against
an object so cast the object (assuming it can be cast) to an int.

so for example rather than:

if(x.Equals(y)) //where y is the object

do

if(x.Equals((int)y)) ///where y is the object

Your error message should indicate which line is the error so just look at
that line first.

I believe your first issue is happenning here e.Item.ItemIndex ==
e.CommandArgument .. make commandargument an integer first (i.e. use
int.parse etc to verify it is of the right type).

if (e.Item.ItemIndex == e.CommandArgument & (e.Item.ItemType ==
ListItemType.Item | e.Item.ItemType == ListItemType.AlternatingItem))
{

string customerid;
customerid = ((Label)(e.Item.FindControl("Label2"))).Text;
DataGrid childgrid;
DataSet ds = GetOrdersDataSet(customerid);
childgrid = e.Item.FindControl("DataGrid1");

Change to
childgrid = (DataGrid) e.Item.FindControl("DataGrid1");

childgrid.DataSource = ds;
childgrid.DataBind();
childgrid.Visible = true;
((LinkButton)(e.Item.FindControl("LinkButton1"))).Text = "Hide Orders";
((LinkButton)(e.Item.FindControl("LinkButton1"))).CommandName =
"hideorders";

}

else
if (e.Item.ItemType == ListItemType.Item | e.Item.ItemType ==
ListItemType.AlternatingItem)
{
DataGrid childgrid;
childgrid = e.Item.FindControl("DataGrid1");

Change to
childgrid = (DataGrid) e.Item.FindControl("DataGrid1");
